Ledger Login — Ledger Developer Portal

This document guides developers through the secure login process and integration points within the Ledger ecosystem.

1. Authentication Overview and Protocols

Understanding the necessary steps to authenticate your application with the Ledger Developer environment is critical for seamless integration. We primarily rely on OAuth 2.0 and API keys.

1.1. OAuth 2.0 Flow Implementation

Details on setting up your client ID and secret. The authorization grant flow is the recommended path for most third-party applications.

1.1.1. Obtaining Your Client Credentials

You can register your application on the Developer Console (Link 1). Ensure your redirect URI is correctly configured.

Required Scopes and Permissions

Access tokens are scoped. Review the official documentation on required scopes (Link 2) before initiating the login request.


2. Developer Resources and Links

Here are several key links to documentation, support, and necessary tools. Each link is styled with the official Ledger color for visibility.


3. ❓ Frequently Asked Questions (FAQ)

Common questions regarding the login and developer account management.

Q: What is the maximum session duration for an access token?

A: Access tokens expire after **60 minutes** for security. You must use the refresh token endpoint to obtain a new one before expiration.

Q: How do I reset my API key if it's compromised?

A: Log in to the Developer Dashboard, navigate to the 'Security' tab, and click the 'Regenerate API Key' button. This immediately revokes the old key.

Q: Is the Ledger Nano device required for development/testing?

A: While some integrations require a physical device, many initial testing phases can be done using the Ledger Live desktop emulator. Consult the SDK guide for specifics.
